Yes, NIT does offer an integrated course of B.Sc+M.Sc.

Dear,
Integrated M.Sc B.Ed in chemistry is available in Central University Rajasthan.
Eligibility:
1. You have to complete B.Sc in Chemistry as one of the main subjects with 50%/45% (for SC/ST/OBC.
2. You have to qualify CUCET exam.
Best wishes.

In my opinion, better don't waste your time leaving the existing course and again preparing for JEE. If you have that much interest and dedication, prepare in parallel without leaving your present course.

EMPI is the best option for Business Analytics degree course.
